Sensorex to Showcase pH/ORP Transmitters at WEFTEC

Sensorex will showcase its TX2000 Intelligent pH/ORP series transmitters at WEFTEC 2014 in New Orleans. WEFTEC, taking place from Sept. 29 to Oct. 1, 2014, is the world’s largest annual water quality conference and exhibition.

Influent process monitoring can alert water treatment plant operators to contaminated raw sewage entering the plant, allowing it to be diverted and further treated to avoid process upsets. Measuring pH in raw sewage can detect excess acid or base conditions that may be the result of a municipal spill or large industrial user discharge. The pH of discharge water must also be monitored to comply with local regulations. In plants using biological treatments, ORP (redox) measurement is frequently used for process control. Full featured with alarm/control relays and current outputs (4-20mA), the TX2000 transmitter interfaces to plant SCADA or DCS control systems, keeping operators apprised of changing process conditions.

The transmitter features easy-to-navigate text and graphic illustrations in a large display, backlit for operation in low light conditions. Supplied in a compact NEMA 4X/IP65 enclosure, units can be wall mounted, installed in a panel, or conveniently pipe/handrail mounted.

An optional TX2000RS model offers additional features including data display charts and trend graphics, a real-time clock with logbook function, and customer defined five-point calibration with displayed calibration curve. The RS model is also equipped with one analog output and serial RS-485 interface for MODBUS RTU or ASCII communications, for digital interface to existing plant SCADA or DCS control systems.

Both models are CE certified and include Multi-Cal calibration with automatic buffer recognition, an additional wash feature, and universal 100-240VAC power supply. The TX2000 has a pH measurement range of -2.00 to 16.00pH and an oxidation reduction potential (ORP) measurement range of -1999mV to 1999mV. The transmitters are compatible with a number probes and sensors to fit most process application requirements.
